People with 'Airy' Moon, (Gemini, Libra or Aquarius) will need to communicate to others their ideas, opinions, ideals, knowledge or beliefs to others in order to feel right about themselves. Finding out, learning and passing on information on will be nourishment for them, as well as a good conversation with like-minded or intellectual people. Curiosity and the need to know could be the thing that forces them out their comfort zone. Negatively they could be too influenced by others options, be indecisive or simply a 'gossip'.
Other than the sun, no other celestial body significantly affects the earth as the moon does. It is well know that the moon affects the rise and fall of the ocean tide. Such is the effect of the gravitational pull between the earth and the moon. Jupiter is easily the largest planet in our solar system. To put its size in context, Jupiter is more than 300 times the mass of Earth. Here is the interesting part; Jupiter has 63 moons that orbit it and yet it is not the planet in the Solar System with the most moons. That honor belongs to the ringed-planet Saturn, which has 66 moons identified so far. Pluto, the farthest flung among the nine planets, has been the subject of heated debate on whether it really qualifies to be considered a planet. Nowadays, it is classified as a dwarf planet. Its orbit around the Sun is somewhat heavily elliptical. In fact, there are instances where Pluto is actually closer to the Sun than Neptune, the planet that precedes it.
